Software-Defined CDNs: Scale and Quality at a Savings

Posted on by

Ustream has earned a reputation for being able to accommodate some of the world’s largest streaming events with as many as 1 million concurrent viewers and 14 million total viewers during large events and regularly hosts 70 million viewers per month. And, while that alone is impressive, what’s more interesting is that Ustream has developed technology that meet the needs when audiences start quickly, grow quickly and then leave once the live event is over.

Enormous audiences like these bring with them several challenges.

  1. The need to use more than one CDN provider to cover all viewers in all parts of the world
  2. The need to ensure HD quality playback for each individual viewer, with as little buffering as possible, regardless of where they are or what type of device they’re using
  3. The ability to do both of the above without breaking the bank. While it is always possible to add additional servers or CDN capacity to accommodate the peak usage pattern, that extra capacity is wasted during times of lower usage.

The solution for these problems has been seven years in the making at Ustream. It’s a unique technology we call Software Defined CDN, or SD-CDN. This blog from online video “voice of the industry” analyst and blogger, Dan Rayburn speculates on the possibilities of this technology platform as a stand-alone service or bandwidth exchange. The edited excerpts below from Rayburn’s blog provide more specifics details.

What Is the SD-CDN?

Ustream’s SD-CDN offers:

  1. The ability to scale automatically without manual provisioning of resources, dynamically adding and removing edges and providers as needed
  2. The ability to leverage a combination of edge resources — including CDN providers, transit lines, and peering and ad-hoc edges — including those located inside an ISP’s network on inside a private network (such as an enterprise network). A new edge resource can be registered and serving traffic in less than one minute.
  3. The ability to flexibly and instantly route traffic among any of these sources based on a combination of rules to maximize resilience, quality and cost
  4. Built-in monitoring to evaluate the performance and efficacy of competing sources — on a global scale or down to the individual viewer
  5. The ability to tweak business logic in real time if scale, quality or cost is jeopardized by changing conditions.

How Does the SD-CDN work?

The SD-CDN works by deploying a software layer that transmits, receives and processes metadata between sources of video content (streaming servers, CDN edges, transit lines, ad-hoc edges) and destinations (end-user viewing devices).

Each Ustream player that is deployed has a connection called the Ustream Media Server connection (UMS), which sends back real-time data each second. This creates an enormous amount of data, as each connected player is sending back-real time status updates — even if it is not yet playing or has stopped playing the video content.

This connection delivers messages in both directions. For example, the player reports back its IP address to the SD-CDN, and logic can be triggered based on that data (such as whether the viewer is in a restricted country or not). The same connection can be used to deliver data about whether or not that player is buffering.

This data is all processed at a few geographically distributed locations (to ensure redundancy) and is analyzed in real time using proprietary. The algorithms contained in the SD-CDN central servers look at things like whether a player is buffering and whether it is affecting just one client or if there is a pattern of buffering in a specific region.

Since switching between sources can occur on the level of a single client, the SD/CDN can address an isolated issue with a client side switch. But if a large number of client-side switches are being reported, then the SD-CDN can make a large-scale switch to completely disable a certain CDN provider or a certain ad-hoc edge if necessary.

In addition, since the SD-CDN includes monitoring capabilities, the automatic logic can always be overridden or augmented by real-time monitoring at Ustream’s Network Operations Center (NOC). A network operations expert can spot a pattern not picked up automatically by the algorithms and use the interface of the SD-CDN to take instant control of the entire system. Over time, as new patterns emerge, they are added to the SD-CDN’s automatic recognition algorithms.

The SD-CDN is particularly beneficial when used in concert with Ustream’s other streaming technologies. For example, Ustream offers a cloud transcoding service that allows users to send a single high-bitrate HD stream. Ustream generates lower bitrate and lower resolution versions of the stream; when these versions are created, time synchronization markers are added as metadata in the stream. This is important for switching between bitrates on a single player from a single source, to ensure the stream content does not jump or skip back in time, but these markers also allow the Ustream player to actually perform a seamless switch between streams coming from two completely different sources.

The SD-CDN can adapt to provide the best possible quality for each individual viewer or to make changes on a larger scale that pre-empt an issue before the viewing client reports it. In addition, the SD-CDN can manage traffic across a network of CDN providers, transit lines, peering and ad-hoc edges based on the cost considerations of carrying traffic of a given volume at any given time.

If you’re familiar with CDN pricing and contracts (if not, you might find this page helpful), you’ll recall that content providers are expected to predict in advance the amount of usage they will have on a monthly basis and to sign a long-term contract based on those predictions. It is typically a “use it or lose it” proposition, whereby overestimating usage will result in sunk cost with no ROI, and underestimating usage can lead to steep overage fees.

In addition, the content provider is incentivized by way of scaled discounts to commit to a larger package because unit economics become more appealing when buying in bulk. The rules of this game make it a tricky proposition for any content provider wanting to maximize the value of its investment in a third-party CDN service.

This is one of the key advantages the SD-CDN can provide. This is one of the key advantages that Ustream’s SD-CDN can provide. For several months, Ustream has been able to utilize third-party CDN services at a flat 95/5 usage pattern. This results in an optimal ROI in the contracts Ustream has with third-party CDN and transit providers. This cost savings can then be passed on to viewers, which is one of the reasons Ustream is able to offer the same scale and quality of delivery as many leading CDNs, even at lower costs.

The Future of the SD-CDN

While Ustream has used this solution extensively for delivery of video content, it is in fact content type–agnostic and can be put to work for any kind of HTTP traffic, such as gaming or any Web-based application acceleration. Ustream is currently using the SD-CDN to control all of its video content and is considering offering the solution as a stand-alone service for others with similar needs.

The Politics of Mobile Streaming

Posted on by

Live mobile broadcasting was one of the hottest topics at last week’s South by Southwest event. And while live video — even mobile live video — is nothing new, conversations around its applications are springing up in several sectors, including politics.

Some pundits are holding up the latest mobile streaming video apps as political game-changers as the 2016 election season approaches. Are they right?

Not quite, says Matt Browner Hamlin in a recent article on Medium. Smart campaigners have actually been leveraging the power of live video streaming since the very beginning. Hamlin goes on to describe how he, as deputy Internet director for Christopher Dodd’s campaign way back in in 2007, Ustreamed speeches and Q&A sessions:

People following the presidential primary were able to engage in the same dialogue with a candidate as residents of the early states. Using UStream’s embedded chat functionality, as well as monitoring comments on the sites where our streams were embedded, we were able to bring in questions from people across the country into Dodd’s Q&A sessions with voters in New Hampshire and caucus-goers in Iowa.

Ustream: Mobile Since 2009

Posted on by

If you kept up with some of the discussions at South by Southwest (SXSW) this past week, you surely noticed a lot of buzz around live streaming video from mobile devices. And while some are talking about mobile streaming like it’s cutting-edge stuff, you might be surprised to learn that Ustream has been doing this for years.

Back in 2009, Ustream introduced the world’s first mobile app capable of streaming live video from the iPhone to the Internet. Almost six years later, it seems the rest of the world is finally catching up.

Since its introduction, Ustream Live Broadcaster has seen more than 15 million downloads and last year, Ustream delivered more than 75 million mobile live broadcasts.

In a recent conversation with Will Oremus of Slate magazine, Ustream CEO Brad Hunstable shared that he isn’t surprised by the sudden success of other mobile apps, nor is he worried.

And yes, he thinks casual mobile live streaming is here to stay. “It’s a different thing, like Vine versus YouTube,” he said of the difference between Meerkat and Ustream. In his view, Meerkat will bring attention to live streaming and lower the barrier to people creating videos themselves, and that will benefit the whole sector. Between the coming 5G mobile data networks and cameras that can shoot 1080p video, he said, “there are a lot of very natural forces that are pushing this industry toward an explosion.”

Not that Ustream is resting on its laurels. Earlier this week, Ustream opened its live mobile broadcasting SDK and APIs to the public, allowing any company to build a Meerkat-like or other creative live video solution and to leverage Ustream’s live video platform for immediate scalability. TechCrunch’s Kyle Russell broke the news for Ustream in this article which was shared and gained enough traction for the SDK to land on new tech product sharing site Product Hunt and gain upvotes from around the world. Click here to cast your vote. The APIs and SDK will be free for developers to use in creating and testing their applications.

So while a couple tiny startups ride the media wave from SXSW, we’ll continue to innovate on the proven, technology platform that started it all. As noted in last week’s NPR All Tech Considered article by Tajha Chappallet-Lanier, we’re delivering video solutions highly tailored to the needs of marketers, executives, HR professionals, and professional broadcasters. And, we’ll adding powerful, enterprise-class features like security, SD-CDN, eCDN and SSO that enable organizations to use business-ready video solutions.

Super Bowl Highlights Need for Scalable Streaming

Posted on by

When the New England Patriots squared off against the Seattle Seahawks in Super Bowl XLIV, more than 1.3 million people experienced the event through NBC’s live streaming video — a 50 percent increase over last year’s online viewership.

According to NBC’s press release, the stream also set Super Bowl records for average viewers per minute (800,000), concurrent users (1.3 million) and total minutes (213 million).

While it was an impressive achievement for live streaming video, it was not without its challenges. As the game progressed, the overwhelming demand resulted in some online viewers experiencing time delays and other technical difficulties.

“NBC is great at streaming live events,” Ustream CTO Gyula Feher told The Daily Dot in an interview regarding the event. “They were the first to stream the Super Bowl in 2012. And, the Super Bowl is the ‘Everest’ of live events: Let’s remember that Super Bowl XLVIII was the most watched television event ever. It’s likely that the peak load on the NBC livestream was similarly record-breaking.”

One of the biggest challenges in streaming a live event, however, is anticipating the bandwidth required, which can vary dramatically from one minute to the next. For example, during Salesforce’s Dreamforce conference, the streams of keynote speeches by CEO Mark Benioff and Hilary Clinton drew record-setting audiences.

One way Ustream has addressed this challenge of being able to scale and anticipate required bandwidth is through a unique technology we developed called Software Defined content delivery network (CDN), or SD-CDN.

SD-CDN provides the ability to scale automatically without manual provisioning of resources, dynamically adding and removing edges and providers as demand requires. The system can leverage a combination of edge resources (e.g. CDN providers, transit lines, peering and ad-hoc edges, etc.) and instantly route traffic among those sources as needed. A built-in monitoring system evaluates in real time the performance and efficacy of each source and can make automatic adjustments as changing conditions require.

What does all this mean for the individual viewer? The best possible quality from beginning to end — and the ability to pre-empt issues that could disrupt the viewing experience.

Now that’s what we call a big win.

Is 2015 “The Year of Video?”

Posted on by

When that famous ball dropped in Times Square to mark the start of 2015, millions of viewers around the world had access to the event thanks to Ustream’s six-hour live streaming broadcast. It was a most appropriate beginning to what Ustream CEO Brad Hunstable is calling “The Year of Video.”

“I think 2015 will be the year of video,” Hunstable recently told the International Business Times, “so it’s sort of fitting that we bring this into the new year with this really interactive, really HD, high-quality New Year’s Eve presentation.”

So what is driving this surging interest in live streaming video? One word: business.

“The business model for Ustream has been traditionally advertising,” Hunstable said, “but what’s interesting is over the past few years we’ve really doubled down our efforts to become a SAAS [Software-as-a-Service] company. We’ll license and sell our technology to media companies and enterprises that need really powerful and highly scalable video solutions.” (Read the full article here.)

Hunstable echoed those same sentiments when he spoke with SiliconANGLE at IBM Impact 2014:

“If you look at where the growth is happening in video — most people don’t realize this — most of the growth in this next wave is going to happen within the enterprise … The enterprise is a tremendous opportunity, and what you’re going to see coming from Ustream, we’re going to continue to provide really robust solutions that solve the needs of these organizations for productivity, transparency, to connect with consumers and their employees in deeper ways … Every corporation today is a media company.”

The data supports Hunstable’s assertions: According to a recent study by The Aberdeen Group, 95 percent of Best-in-Class marketers are using video as part of their content marketing mix.

So, will 2015 be “The Year of Video?” We think so!

Brad Hunstable to ReadWrite: “Video can really relay passion better than any medium”

Posted on by

Ustream CEO Brad Hunstable recently sat down with Stephanie Chan of the tech news site ReadWrite to share the story of Ustream, what the company is like today, and where it — and live streaming video in general — is going. (Read the full article here)

Some of our favorite excerpts:brad-hunstable-readwrite

ReadWrite: What were you like growing up?

Brad Hunstable: I was definitely more of a hacker as a kid. As a pre-teen, I coded and built a Bulletin Board Service (BBS – the Internet before there was an Internet) in Texas. […] It certainly was not “cool” to be a programmer back then and the many times I was called ”geek” were not terms of endearment.
***

RWCan you tell me what Ustream is like today? 

BH: Ustream is one of the largest video solutions on the Web, and we are primarily focused on enterprises. We want to help businesses communicate more effectively with their two most important constituents— customers and their employees.

***

RW: Livestreaming has recently come into the media forefront with Amazon’s acquisition of livestream video gaming site, Twitch. What does this mean for the current state of livestream video?

BH: […] Video is reaching a point where it’s really becoming a foundation piece of the Internet. By 2017, according to Cisco, it will be 55% of the Internet’s traffic. It’s incredible. We did a Sony Playstation 4 launch a couple months ago, and it was 2% of the Internet’s traffic.

***

RW: What’s next for you and Ustream?

BH: I’m a big believer that there’s going to be a company that can be a video layer across enterprise. Everything I’m doing today in terms of our product is really about helping businesses be more transparent to their customers, more transparent to their employees. We help them use video to build those relationships.

How a Webcam Pointed at a Police Radio Won the Internet Friday – All Things D

The events in Boston — starting Monday with a pair of explosions that killed three and injured 176 near the finish line of the Boston Marathon — came to a dramatic close Friday night with the capture of 19-year-old Dzhokhar Tsarnaev, one of two brothers suspected of carrying out the attacks. He had been hiding out in a boat parked in the backyard of a house in Watertown, Mass.

A furious citywide manhunt brought Boston and surrounding towns to a standstill, and there was little else to do all day but watch the live TV coverage. All day, reporters repeated what they knew, which was precious little beyond the bare facts. One suspect was dead, the other on the run after an intense gunfight with police. The “Breaking News” banners became meaningless, because throughout the day there was not much actual news breaking other than that the search continued.

Not 30 minutes after a news conference during which local officials told Boston residents they could probably go outside again, police engaged in a firefight with the suspect hiding in the boat.

It was at this point that a quarter of a million people, including me, tuned in to the streaming video image of Uniden Bearcat scanner radio picking up publicly available police communications traffic in Boston.
